I have my injectors out and the grommets and O rings i got from Toyota look correct except the insulators that seats them into the head look different and there does not seem to be anything to remove from the injectors unless they are hardened and fused onto them. I double checked the part number with Toyota and they claim it is correct. I thought there was suppose to be an O ring on the bottom side of the injector as well but not seeing it unless its hardened and fused as well. adding some pictures so yall can see what i am seeing. Thanks for any help in advance.
